Novel chloroacetanilide derivatives and herbicides containing the same for use in paddy field

Abstract

Disclosed herein are novel chloroacetanilide derivatives which act as remarkably effective herbicides when sprayed in a paddy field, the chloroacetanilide derivatives being 2',6'-diethyl-N-[(cis-alkenyloxy)methyl]-2-chloroacetanilides [A] represented by the general formula <IMAGE> [A] wherein R is a cis-form alkenyl group having 4 or 5 carbon atoms. Also disclosed are herbicide compositions for use in a paddy field and containing at least one of said chloroacetanilide derivatives [A] and at least one pyrazole derivative [B] represented by the general formula <IMAGE> [B] wherein R is a hydrogen atom or methyl group and X is a 4-toluenesulfonyl group or benzoylmethyl group; or- alpha -(2-naphtoxy)-propyonanilide [C] represented by the formula <IMAGE> [C]

We claim: 
     
       1. A herbicide for paddy fields containing 2', 6'-diethyl-N-[(2-cis-butenoxy) methyl]-2-chloroacetanilide represented by the formula ##STR14## as its active ingredient. 
     
     
       2. A herbicide composition for paddy fields containing 2', 6'- diethyl-N- [(2-cis-butenoxy) methyl]-2-chloro-acetanilide and 1,3-dimethyl-4-(2,4-dicholorobenzoyl) -5-pyrazolyl-4-toluenesulfonate as its active components. 
     
     
       3. A herbicidal composition for paddy fields ontaining 2',6'-diethyl-N- [(2-cis-butenoxy) methyl]-2-chloroacetnilide and '-(2-naphthoxy)-propionanilide as its active components.
